With a 47V reverse standoff voltage and 53.2V minimum breakdown, it sits above a 48V DC bus or a 28V AC line, staying transparent during normal operation and only conducting when a surge pushes the rail above the breakdown threshold. ## Clamping and pulse current — what the numbers mean for your board When the 1N6057A/TR fires, it clamps the transient to 77V maximum at the rated 19.5A peak pulse current — that 77V ceiling is the voltage stress the downstream components must survive during the surge event. The single bidirectional channel means one device protects a differential pair or an AC line against both positive and negative transients, saving board space versus two unidirectional TVS diodes back-to-back. No power line protection (the part is not designed for continuous overvoltage clamping on a power rail) — its role is transient suppression, not regulation. ## Active production — no last-time-buy pressure General-purpose application classification means it is not restricted to a specific qualification flow — but the DO-13 hermetic package is a known high-reliability form factor used in MIL-STD-750 screened builds.","metaTitle":"1N6057A/TR TVS Diode - 1500W Bidirectional Zener, DO-13","metaDescription":"1N6057A/TR bidirectional Zener TVS diode, 1500W peak pulse power, 47V standoff, 53.2V breakdown, 77V clamp.
